Retro-transposon transporting motif This is the highly conserved C-terminal motif GRKIxxxxxRRKx of nucleoporins that plays a critical and unique role in the nuclear import of retro-transposons in both yeasts and higher organizms. It would appear that the arginine residues at positions 2 and 9-10 constitute a bipartite nuclear localization signal, with two basic peptide motifs separated by an interchangeable spacer sequence, that is crucial for the retro-transposon activity. |
